"His (Dr. Ambedkar's) personality, erudition and capacity to lead and organise-would have by themselves marked him out as an outstanding asset to our nation. But in addition to that the in-estimable services he has rendered to our motherland in trying to stamp out untouchability and the result he has achieved in instilling a manly spirit of self-confidence in millions of the depressed classes, constitute an abiding, patriotic as well as humanitarian achievement. The very fact of the birth of such a towering personality among the so-called untouchable castes could not but liberate their souls from self-depression and animate them to challenge the super-arrogative claims of the so-called touchables."
